drm/amdgpu/nv: Apply ASPM quirk on Intel ADL + AMD Navi

S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is
caused by commit 0064b0ce85 ("drm/amd/pm: enable ASPM by default").

The root cause is still not clear for now.

So extend and apply the ASPM quirk from commit e02fe3bc7a
("drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems"), to
workaround the issue on Navi cards too.

Fixes: 0064b0ce85 ("drm/amd/pm: enable ASPM by default")
